' WINDOW GUIDE.

Application filed May 18,

a cushioning material, such as felt or rubber,

and those in which the glass is directly engaged by resilientmetal. Of the first mentioned type, where felt is employed, the felt is usually placed either directly in the cas. ing groove, or it is placed in metal channel which is in turn secured in the casing groove,

and my present invention more specifically relates to the lattertype in which the metal channel and felt lining are combined.

The guides of the type last referred to, which have been extenslvely used, have-comrised a metal strip bent in U-form, said strip liaving its edges inturned to provide recesses in which the edge portions of the felt strip are located to hold the latter in position therein. Guides of this form have been found objectionable principally because the glass plates in connection with which they are used must be graded as to thickness, as

.it is impractical to use mill-run glass,

which varies in thickness, but is less expensive, in connection therewith. The felt cushioning strip is not held with suflicient security against longitudinal slipping in the metal channel, being merely held by, frie tion, and the friction of the glass on the felt, as itv is raised or lowered, tends to cause the felt to slide longitudinally of the channel strip, so that, if, by reason of moisture or other cause, the felt should adhere to the glass, there is great liability that the felt will be pushed into bunches and the glass caused to bind. Also with said prior construction it hasbeen' considered neces-. sary to lace the felt in the metal channel before the latter is secured in the window casing, and, as the screw holes in the channel, through which screws are passed to.

secure it, are covered with the felt lining,

5 delay is causedin finding these holes after 1924. Serial No. 713,088.

the channel has been placed in position. Moreover, as it is difiicult or impractical to place the felt in the channel after installation of the latter, it is'equally diflicult to renew the felt when renewal is necessary.

The objects of my invention are to provide a form of window guide of the. felt lined metal channel type in which a strip of felt of uniform width and thickness may.

be readily placed in the channelafter the channel has been secured in position in the window casing, and which, by the operation of pushing it into the channel, will practically be automatically secured therein and 9 held both against outward movement from the channel bottom and against movement longitudinally thereof, but which may be readily removed in case renewal is necessary. 4 Also to provide a felt lined channel which is adapted to receive and satisfactorily guide glass plates of varying thickness.

I accomplish these objects, in a general way, by'providing a resilient metal strip which 1s shaped in approximate U-form, to

provide converging resilient side portions and in the side portions of which a series of pointed tongues or barbs are formed which extend toward the bottom of the channel in position to enter the felt strip,"

when pressed therein and hold it from both lateral and longitudinal movement.

For a more complete understanding of m invention, reference is madeto the accompanying drawing in which:'

Fig. 1 is a side elevation and Fig. 2 is a central longitudinal sectional view of a window guide embodying my invention.

Fig. '3' is a cross section at line 3-3 of Fig.

Figs. 4 and 5 are crosssectional views of a modified form of the invention.

According to my invention, I provide" a strip of resilient sheet metal which is bent to be permanently set in U-form to provide a channel a, which is adapted to be fitted into the guide groove of a window casing 12, so that its bottom portion rests on "the bottom'of the groove and'may be secured v thereto by screws 0, or ,other convenient means. In practice, screw holes d are punched through the bottom inward at suitable intervals so as to form sharp projections on the inner side. When secured in. position, the side portions of the channel strip. bear against the sides of the casing barbs which extend or point towards the bottom of the channel in oblique relation "to the side portions. Said tongues or barbs are arranged in a row at suitable intervals,

for example, an inch or two inches apart at a short distance from the outer edges of the Side portions, but at points opposite the sides of the casing groove. The exact angle at which the tongues extend from the s1de portions is not essential, but they must extend inward at angle to the sides and towards the bottom, approximately the angle shown being preferable.

In the form of my invention shown in Fig. 3, the edge portions of the sides of the channel are rolled inward to form a cylindrically shaped edge bead g, which is approximatel flush with -the surface of the casing, an in the form shown in'Figs. 4 and 5, the edge portions of the channel strip a are rolled outward to form cylin drically shaped edge beads k, which are 10- .cated ust beyond the surface of the casing and are of suflicient diameter to extend laterally to the extent with which the corresponding side of the channel diverges from \t e sides of the casing groove, when a window glass sheet of minimum thickness is inserted thereini Inwardly projectin barbs 0', similar to .barbs e, are formed in the side portions in the manner already' described.

After the metal channel-a has been secured in csition in the casing groove, as

. shown in ig. 2, a felt strip 6, of a suitable aimform width and thickness, is pressed into the channel by placing'it thereon, so that its middle portion 1s opposite the mlddle of the channel, and .then pressing the felt strip urpose, so that the mid le ortion of the elt cov- (EIS the 'bottomof t e channel and its side portions rest a ainst the side portions of the fchannel while its-edges abut with the heads ,9, in the construction of Fig. 3, or are ap- "proximately flush with the outer surface (of .the casing, with the construction of Figs. 4 and 5. As the tongue or barbs e, or e are sharp and project into the channel, the

will penetrate the felt and securely hold 1t :zgamst movement away from the bottom of e channel and also from movement longi- -.tudinally thereof. The barbs in no way mterfere with the insertionof the felt stri fhut engage therein %'lactically automatica l- El y as it is inserted. e projections formed by punchlng the holes at cooperate with the bar s-to hold the felt against longitudinal ihppmg. While the barbs penetrate the felt .nel, to penetrate the linin to a sufficient extent to hold it in the position in which it is laced, the felt may be removed without ifliculty by tearing it loose from the barbs, and a new felt placed in position in the manner already, described.

As thus arranged, the felt provides a cushion for the sides and edges of .the glass plate, and the arrangement is such that when glass of minimum thickness is placed in position, the sides of the channel strip ,1

will be but slightly separated, if they are.-

separated at all, and, in such case with the construction shown in Figs. 4 and 5, the beads on the edges of the channel will cover the space between the side portions and the sides of the casing grooveas shown in Figs 4. If a thick sheet of glass is inserted, the channel side portions will be ressed aside to the extent necessary to recelve the same and as the edge beads in the construction of Figs. 4 and 5 are held beyond the side of the casing, they will not prevent such-spreading of the side portions even if said side por-- tions arepressed a ainst the sides of the casing groove, as in ig. 5. Obviously the inturned heads 9 do not interfere with the spreading of the sides, as they partly'overlap the edges of the felt and assist in retaining the felt in position.

Under all conditions a cushioning support is provided for the glass, due, in art, to the cushioning effect of the felt, an the further fact that the felt is resiliently supported by the sides of the-metal channel.

I claim:

shaped metal channel adapte lining of cushioning material and having a seriesof pointed tongues formed from each side thereof arranged to extend inwardly therefrom towards the bottom of the chanagainst outward and longltudinal movement'.
